Abstract
A pre-combustion chamber is adapted to be installed in the spark plug well of an existing engine. The pre-combustion chamber includes an inner combustion chamber housing and an outer cooling jacket housing. The two housing are assembled in such a manner to permit movement therebetween during thermal cycling to minimize stress and fatigue fracture. A resilient seal is installed between the housings.
Claims18
A pre-combustion chamber apparatus adapted to be retrofit into the spark plug well of an existing engine, the precombustion chamber including:
- a. an inner combustion chamber housing have a fuel inlet and an igniter connector, the inner combustion chamber housing including an outer wall;
- b. an outer cooling housing substantially surrounding the inner combustion chamber housing and having an interior wall;
- c. a connector secured to and in communication with the interior of the inner combustion chamber and adapted for mounting the pre-combustion chamber in the spark plug well of the engine;
- d. a permanent securing and sealing element for securing a portion of the cooling housing to the combustion chamber housing;
- and
- e. a resilient seal positioned between the outer wall of the combustion chamber housing and the cooling housing for defining a cooling jacket chamber therebetween, sealed and closed by the seal and the permanent securing element.
A pre-combustion chamber apparatus adapted to be retrofit into the spark plug well of an existing engine, the precombustion chamber including:
- a. an inner combustion chamber housing having a fuel inlet and a spark plug well, the inner combustion chamber housing including an outer cylindrical wall portion;
- b. an outer cooling housing substantially surrounding the inner combustion chamber housing and having a interior cylindrical wall portion;
- c. a connector secured to and in communication with the interior of the inner combustion chamber and adapted for mounting the pre-combustion chamber in the spark plug well of the engine;
- d. a portion of the cooling housing permanently welded to the combustion chamber housing;
- and
- e. a resilient seal positioned between the outer cylindrical wall portion of the combustion chamber housing and inner cylindrical wall portion of the cooling housing for defining a cooling jacket chamber therebetween, sealed and closed by the seal and weldment.
A method for assembling a pre-combustion chamber apparatus of the type including an inner pre-combustion chamber housing and an outer cooling jacket housing, the method comprising the steps of:
- a. first finishing the pre-combustion chamber housing;
- b. thereafter installing a resilient seal on the exterior of the pre-combustion chamber housing;
- c. thereafter installing the cooling jacket housing over the pre-combustion chamber housing and the seal;
- and
- d. permanently securing the cooling jacket housing to the pre-combustion chamber housing.
